how to display multi level collection in Gallery

(0) ShareShare

Posted on by F_Quint 257

Hi all, 

 

I have a collection called Eval

 

and the first layer is entities.

from there it can go even deeper. 

 

Eval->entities->Answers->questionGroupScore->questionScores

 

 

What would be the best way to display to level information and be able to drill down to the last level? 

 

if I were to use a Gallery, what would be my items property ? do I need to set up cascading galleries?

    Hi @F_Quint 

    You want to used nested Galleries. So make your 'parent' gallery (probably best to go with a flexible height gallery) with its Items property Eval, then place another Gallery inside and set the Items property to Answers.

    As Answers is a table, you will then be able to add labels to show the fields that make up the Answers table.

    With the Flexible height gallery you can set the Height of the child gallery to the number of rows multiplied by the TemplateSize (+ TemplatePadding) of the child gallery so you don't end up with scrollbars within scrollbars.

    thanks for the reply @Paul 

    I tried your suggestion and for some reason my second nested gallery doesn't recognize answers as a sublevel.  but as you can see from my collection it does exist.

    I think your fomula in the child gallery should just be ThisItem.answers (it is the answers table for the current row/item).
